PATENT OFFICE RALPH HAMILTON BEACH, OF ROYAL OAK, MICHIGAN, ASSIGNOR, BY MESNE ASSIGN- MENTS, T INTERNATIONAL RADIATOR CORR, OF PORT CHESTER, NEW YORK., A

CORPORATION OF NEW YORK TEMPERATURE-CHANGING UNIT Application filed July 22,1927, Serial No. 207,755. Renewed October 9, 1929.

My invention relates to improvements in rected to that type of unit wherein a heating medium is used for increasing the temperature of a room or the like.

The object of my invention is to provide a heating system wherein the elements used therein for distributing the heat are constructed in a simple and eiiicient manner,

and more particularly embodies the main features disclosed in my copending application filed January 31, 1927, and bearing Serial No. 164,947.

The invention as set forth in this application includes a heating unit which is composed of a plurality of pipes having thereon fins, the pipes serving to conduct a heating medium, While the fins are adapted to conduct the heat from the pipes and are so positioned that circulation of air thereabout will carry off heat from the fins.

The principal object of the present invention is to provide a unit of the type described which is composed of a series of flattened pipes and which are connected by suitable connections of the type hereinafter described and'which constitute the salient points of this application. 4

Still another object of my invention is to provide a special fin which is adapted to be secured to theexterior of a flattened pipe to conduct'therefrom the heat which may be within the pipe. 1

With these and other objects in view, the invention consists in a general arrangement and combination of parts which will be hereina'fter more fully described in the following specification and specifically set forth in the appended claims when taken in conjunction with the accompanying drawings, in which Figure 1 is a side elevation of my improved heating unit.

Figure 2 is a plan view illustrating the type of fin employed. 5

Figure 3 is a side elevation of the fin d1sclosed in Figure 2, and

Figure 4 is a view showing in perspective the various forms of my improved connections.

Referring to the accompanying drawings in detail wherein like reference characters denote corresponding parts throughout the several views, the numeral 1 indicates in As disclosed in Figure 1, the heating unit is composed of a plurality of pipe sections 3, each section being formed of a flattened tube and spaced apart from each other and connected to the common supply pipe 2 by suitable connections which I will hereinafter more fully describe.

As disclosed in Figure 4 wherein I have illustrated the various embodiments of my Invention, it will be noted that I have proyided a T connection 4, the leg 5 of which is internally threaded and receives therein the supply pipe 2. The legs 6 and 7 which are arranged at right angles to the leg 5 are likewise internally threaded and receive therein the threaded end of a nipple 8 which serves to connect to the T 4 either of the legs 9 or 10. The T 4- is further provided with an elongated opening 11 which is foi'med, integral therewith and is so positioned with respect to the body 4 of the T that its face projects outwardly from the peripheral face of the body 4. The opening 11 receives therein the end of a pipe section 3 and when this pipe section 3 is positioned therein a suitable connection is formed by welding or any other desired method. As disclosed in Figure 1, the nipple 8 has connected thereto the connection 9 which is likewise formed with a cylindrical body 12 which is interiorly threaded to receive the end of the nipple 8 and is further provided with an elongated opening 13 which receives therein one end of fIiOm the unit condensation which has taken ace.

p It will be noted from the drawings that each of the connections 4, 9 and 10 is provided with a sloping Wall passing from the upper portion of the elongated opening and falling back into the body of the connection, thus presenting a gradual slope from one part of the flattened pipe to the cylindrical body of the connection.

Each of the pipe sections 3 has positioned thereabout and spaced equidistant thereapart a plurality of heating radiating fins 16, each of which is formed of n1etal,-either by casting or stamping from heavy sheet metal and preferablyof rectangular shape, as illustrated in Figure 2 of the drawings: The central portion of the fin 16 is provided with an opening 17 and a flange 18 adjacent the opening, the latter receiving therein the pipe 3 and when the fin is properly placed upon the exterior of the pipe, it may be permanently secured thereto by welding or the like. The fin 16 is further provided with a series of channels 19 which extend about the pipe 3 and serve to increase the area of heat radiating surface and to stiffen the 'fin Having thus fully described my invention Y it will be clearly apparent that when a heating unit is constructed in accordance with the structure disclosed in Figure 1 that by reason of the flattened surface of the pipe sections cold airengaging the lower end or edge of the section will pass up and around the section as illustrated in Figure 1, thus remaining in contact with the pipe section a greater length of' time and thereby insuring a greater heating radiation than in devices wherein a cylindrical pipe section is employed. Furthermore, by reason of the specific connection which I have employed and by slightly inclining the pipe section 3, condensation which occurs within these sections may readily pass back into the line of s pp yi From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention Will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A heating unit of the class described composed of a flattened radiating tube and a supply pipe, and a connection between the tube and pipe having a passageway whose lowest point of drainage is below that of the passageway of the pipe at the point of the tubes and the pipe, said connection hav 'ing an offset inclined ortion within which the tube end is receive and said ofi'set portion directing condensation from the tube into the supply pipe.

In testimony whereof I afiix my signature.

RALPH HAMILTON BEACH.
